To all whom it may concern: 7 1

Be it known that I, FRANK SATz, a citizen of the United States, residing at Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Radiators, of which the following is a specification.

This invention relates to improvements in radiators and it is intended more particularly for use on automobiles.

In devices of this character provision is made for circulation of water through the radiator, and for the'passage of currents of air whereby the circulating water is cooled.

Heretofore it has been the practice to cir culate the water through a series of tubes, and to have the air passages between the tubes, and these passageways between the tubes have been provided with fins.

With this form of construction, 1t has been necessary, when repairs have been ,made, to remove the entire radiator, take the entire device apart, and make the necessary repairs.

In my present invention I also utilize a series of tubes, but in my case I use the tubes for air passageways, while the spaces around and between the tubes is used for the circulation of the water.

Another feature of my invention is to provide for the easy removal of any one of these tubes as a unit.

Another feature is the easy removal of one of the fins from the interior of the tube in which it is located. The invention comprises a series of tubular members, eachof which is provided with a fin member of angular formation, the front and rear ends of the spaces between the tubes being closed by solder, thus forming a water space all around the set of tubes, while each tube is open at both front and rear to permit the free passage therethrough of a current of air, each tube being provided with its individual fin.

The invention is more fully described in the following specification and clearly illustrated in the accompanying drawing, in which Figure 1 is a front elevational view of a radiator, partly broken away to show the water circulation.

Fig. 2 is a partial plan view, looking down from the line 2-2 ofFig. 1.

Fig. 3 is a detail view, showing a portion Specification of Letters Patent.

- of one of the tubular members, slightly enlarged.

The numeral 1 designates the front member of the radiator, having the usual head 2 for holding the tubular members 3 in position. Each tubular member is formed with a series (preferably three) vertical ribs 4 formed on one side thereof, adapted to prop erly space the tubes from each other, and to form the required space for the circulation of water.

Each tube is provided with a removable fin member 5, which fin members are bent to approximately alternate right angles, thus forming, in each tube, a series of substantially tri-angular, horizontal air passageways.

The front and rear ends of the tubes are joined to each other by solder 6, thus closing the spaces between the tubes, and forming thereby, a water space surrounding the tubes. These spaces are open at the top and bottom to permit the water to pass between the tubes into and out of the tank members 7 and 8,,of the radiator.

It is evident that when it is desiredto remove one of the tubes, all that is required is to fuse the solder by a blow torch or other suitable device, and the tube may be removed as a unit.

It is also evident that any of the fins located within the tubes may readily be removed and replaced, for the reason that they are held in position only by friction, being made to fit snugly therein.

It is evident that the vertical ribs 4 will not only space the tubes properly, but they will prevent bulging of the tube walls and insure against accidental closure of the water space between the tubes.

Having thus fully described my invention, what I claim and desire to secure by Letters Patent is 1. A radiator for automobiles, a series of tubular members horizontally arranged, each member having a plurality of vertical ribs on one side thereof adapted to contact with the wall of a neighboring tubular member, thus forming a water space between the said two tubular members and said water space being closed at the front and rear, and a removable fin member located within each tubular member.

2. In a radiator for automobiles, a series of removable, rectangular, tubular, air passage members, horizontally arranged, each members being bent alternately in opposite member having a plurality of vertical ribs directions at approximately right angles and 10 on one side thereof adapted to contact with having frictional engagement with the inner the outer surface of a neighboring tubular walls of thetubularmembers only at their 5 member, thus forming a water space between bent points.

the two tubular members, which space is 7 In testimony whereof I aflix my signature. closed at the front and rear, and a removable fin member in each tubular member, said fin FRANK SATZ.
